• pread() read only xxxx of yyyy

  - by Alix Axel

  Occasionally, nginx doesn't send any data back to the browser (ERR_EMPTY_RESPONSE in Chrome). Upon checking the server error.log, I find these weird messages: 2013/10/20 23:57:40 [alert] 29146#0: *35 pread() read only 4653 of 4656 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" 2013/10/20 23:57:45 [alert] 29146#0: *36 pread() read only 4653 of 4656 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" 2013/10/20 23:58:18 [alert] 29146#0: *38 pread() read only 4650 of 4653 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" 2013/10/20 23:58:18 [alert] 29146#0: *39 pread() read only 4650 of 4653 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" 2013/10/20 23:58:19 [alert] 29146#0: *40 pread() read only 4650 of 4653 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" 2013/10/21 00:02:21 [alert] 29146#0: *41 pread() read only 4629 of 4641 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" 2013/10/21 00:02:21 [alert] 29146#0: *42 pread() read only 4629 of 4641 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" 2013/10/21 00:02:23 [alert] 29146#0: *43 pread() read only 4629 of 4641 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" 2013/10/21 00:02:31 [alert] 29146#0: *44 pread() read only 4629 of 4641 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" 2013/10/21 00:02:46 [alert] 29146#0: *45 pread() read only 4629 of 4641 from "~/htdocs/index.html" while sending response to client, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost" Does anyone have any idea why this happens?

• How do I get a Mac to request a new IP address from another DHCP server running in parallel while Ne

  - by huyqt

  Hello, I have an interesting situation. I'm trying to us a Linux based machine to allow Mac's to Netboot (similiar to PXE boot) by running a DHCP service in parallel with the "global" DHCP server. The local DHCP server hands out IPs in a private subnet, e.g., 10.168.0.10-10.168.254-254, while the "global" DHCP server hands out IPs from the IP range 10.0.0.1 - 10.0.1.254. The local DHCP range is only supposed to be used in Preboot Execution Environment and Netboot. The local DHCP server is something I have control over, but I do not have access to the global DHCP server. I have a filter to only allow members with the vendor strings "AAPLBSDPC/i386" and "PXEClient". PXE works fine, but Netboot has a quirk. The Apple systems that haven't been connected to the network yet can Netboot fine. But once it grabs a "real" IP address from the global DHCP server, it will "save" it and request it the next time we want it to netboot (which the local dhcp server won't give it). This is what I want: Mar 30 10:52:28 dev01 dhcpd: DHCPDISCOVER from 34:15:xx:xx:xx:xx via eth1 Mar 30 10:52:29 dev01 dhcpd: DHCPOFFER on 10.168.222.46 to 34:15:xx:xx:xx:xx via eth1 Mar 30 10:52:31 dev01 dhcpd: DHCPREQUEST for 10.168.222.46 (10.168.0.1) from 34:15:xx:xx:xx:xx via eth1 Mar 30 10:52:31 dev01 dhcpd: DHCPACK on 10.168.222.46 to 34:15:xx:xx:xx:xx via eth1 Mar 30 10:52:32 dev01 in.tftpd[5890]: tftp: client does not accept options Mar 30 10:52:53 dev01 in.tftpd[5891]: tftp: client does not accept options Mar 30 10:52:53 dev01 in.tftpd[5893]: tftp: client does not accept options Mar 30 10:52:54 dev01 in.tftpd[5895]: tftp: client does not accept options This is what I get when it already has a "stored" IP: Mar 30 10:51:29 dev01 dhcpd: DHCPDISCOVER from 00:25:xx:xx:xx:xx via eth1 Mar 30 10:51:30 dev01 dhcpd: DHCPOFFER on 10.168.222.45 to 00:25:xx:xx:xx:xx via eth1 Mar 30 10:51:31 dev01 dhcpd: DHCPREQUEST for 10.0.0.61 (10.0.0.1) from 00:25:xx:xx:xx:xx via eth1: ignored (not authoritative). Do you have any suggestions? It would be much appreciated.

• Web2.0, AJAX, HTML5, Facebook, Social web, openid, Oauth, web browsers... where is all this going ?

  - by jokoon

  We have seen many new things appear in the last 7 or 5 five years on the web: Facebook, html5 appeared, new browsers grew strongly, Google failed with Wave... Since Facebook and other stuff like Gtalk and Gmail, I thought and hoped that forums, chat, mail, usenet, conversation rooms and p2p protocols could inter operate to allow the user to use all those services transparently. Of course I realized that things are far much complicated, for several reasons: the IETF cannot invent new things: they just propose standards. Microsoft as well as big players often are obstacles to relevant innovation regarding open formats. The biggest stories being document formats or internet explorer with its long reaction to support web standards. Smartphones, thanks to the appearances of OSes such as iOS and Android, are finally able to navigate on internet: former devices were deaf, they weren't directly connected to internet. The mail protocol were left unchanged even with the grow of spam and malwares. I don't know what to think, because I think there is still a lot to do, but I feel like it will never happen or that nobody seems interested in those basic text transmit features... So what do you think what are the next big steps in the evolution of the web ? Do you think is will still walk hand in hand with open source ?

• How do I handle a request for "index.php/somepath" in Nginx config?

  - by Arne

  I'm currently attempting to serve Icinga from nginx. The new Icinga-Web ui attempts to load a file from URL http://SERVER/icinga-web/index.php/appkit/squishloader/javascript (leading to a 404). How do I setup a location for this scenario? How do I get nginx to serve index.php and pass the full request path in a way Icinga understands? This is my current nginx config for icinga (adapted from the default apache config): server { server_name SERVER; root /opt/icinga/icinga-1.2.1; location /icinga-web/js/ext3 { alias /opt/icinga/icinga-1.2.1/lib/ext3; } location /icinga-web { alias /opt/icinga/icinga-1.2.1/pub; } location /icinga/cgi-bin { alias /opt/icinga/icinga-1.2.1/sbin; } location /icinga { alias /opt/icinga/icinga-1.2.1/share; } location ~ \.php([\?/].*)?$ { include fastcgi_params; fastcgi_pass 127.0.0.1:61000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; } } Any thoughts? Thanks!

• Retrieve the full ASP.NET Form Buffer as a String

  - by Rick Strahl

  Did it again today: For logging purposes I needed to capture the full Request.Form data as a string and while it’s pretty easy to retrieve the buffer it always takes me a few minutes to remember how to do it. So I finally wrote a small helper function to accomplish this since this comes up rather frequently especially in debugging scenarios or in the immediate window. Here’s the quick function to get the form buffer as string: /// <summary> /// Returns the content of the POST buffer as string /// </summary> /// <returns></returns> public static string FormBufferToString() { HttpRequest Request = HttpContext.Current.Request; if (Request.TotalBytes > 0) return Encoding.Default.GetString(Request.BinaryRead(Request.TotalBytes)); return string.Empty; } Clearly a simple task, but handy to have in your library for reuse. You probably don’t want to call this if you have a massive inbound form buffer, or if the data you’re retrieving is binary. It’s probably a good idea to check the inbound content type before calling this function with something like this: var formBuffer = string.Empty; if (Request.ContentType.StartsWith("text/") || Request.ContentType == "application/x-www-form-urlencoded") ) { formBuffer = FormBufferToString(); } to ensure you’re working only on content types you can actually view as text. Now if I can only remember the name of this function in my library – it’s part of the static WebUtils class in the West Wind Web Toolkit if you want to check out a number of other useful Web helper functions.© Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET

• Ajaxy

  - by Chris Skardon

  Today is the big day, the day I attempt to use Ajax in the app… I’ve never done this (well, tell a lie, I’ve done it in a ‘tutorial’ site, but that was a while ago now), so it’s going to be interesting.. OK, basics first, let’s start with the @Ajax.ActionLink Right, first stab: @Ajax.ActionLink("Click to get latest", "LatestEntry", new AjaxOptions { UpdateTargetId = "ajaxEntrant", InsertionMode = InsertionMode.Replace, HttpMethod = "GET" }) As far as I’m aware, I’m asking to get the ‘LatestEntry’ from the current controller, and in doing so, I will replace the #ajaxEntrant DOM bit with the result. So. I guess I’d better get the result working… To the controller! public PartialResult LatestEntry() { var entrant =_db.Entrants.OrderByDescending(e => e.Id).Single(); return PartialView("_Entrant", entrant); } Pretty simple, just returns the last entry in a PartialView… but! I have yet to make my partial view, so onto that! @model Webby.Entrant <div class="entrant"> <h4>@Model.Name</h4> </div> Again, super simple, (I’m really just testing at this point)… All the code is now there (as far as I know), so F5 and in… And once again, in the traditionally disappointing way of the norm, it doesn’t work, sure… it opens the right view, but it doesn’t replace the #ajaxEntry DOM element, rather it replaces the whole page… The source code (again, as far as I know) looks ok: <a data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#ajaxEntrants" href="/Entrants/LatestEntrant">Click to get latest</a> Changing the InsertionMode to any of the other modes has the same effect.. It’s not the DOM name either, changing that has the same effect.. i.e. none. It’s not the partial view either, just making that a <p> has (again) no effect… Ahhhhh --- what a schoolboy error… I had neglected (ahem) to actually put the script bit into the calling page (another save from stackoverflow): <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script> I’ve now stuck that into the _Layout.cshtml view temporarily to aid the development process… :) Onwards and upwards!

• Mailbox move issue from Exchange 2003 to Exchange 2010

  - by Ryan Roussel

  Today while moving mailboxes between Exchange 2003 and Exchange 2010, I hit an issue with a couple of mailboxes.  These mailboxes all popped access denied errors or more exactly: Insufficient Access Rights to perform the operation.   The cause was similar to the mail flow issue in that inheritable permissions were not turned on for the user object in Active Directory.  This also presented it’s own unique problem in that since the initial move request failed because of permissions, it had to be cleared before a new move request could be created. On top of that, the request did not show up in the EMC.  I used the following process to clear the request, assign permission, then create a new request:   1. First you need to know the ExchangeGUID of the mailbox for the remove-moverequest command.  To quickly get the GUID for a mailbox simply run:         2. Next we need to clear out the move request using PowerShell by running: [PS] c:\>Remove-moverequest -moverequestqueue "mailbox database 1030639620" -mailboxguid 8525686f-d4d3-42b7-92f1-46d77ea841a3   3. Then to re-establish inheritable permissions. This can be done by using AD Users and Computers, switching to View Advanced Features, then under the Security tab of the object.  Click Advanced, then check “allow inheritable permissions of parent to propagate to this object”   4. Once the Inheritable permissions are restored, we need to create a new move request: NOTE:  The EMC can also be used to initiate the Move Request once the permissions are corrected. [PS] c:\>New-moverequest –identity jyoung  -baditemlimit 100 -targetdatabase "mailbox database 1030639620"   And that’s it.  The mailbox should move over smoothly with no access denied error.

• ADFS Relying Party

  - by user49607

  I'm trying to set up an Active Directory Federation Service Relying Party and I get the following error. I've tried modifying the page to allow <pages validateRequest="false"> to web.config and it doesn't make a difference. Can someone help me out? Server Error in '/test' Application. A potentially dangerous Request.Form value was detected from the client (wresult="<t:RequestSecurityTo..."). Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. To allow pages to override application request validation settings, set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0". Example: <httpRuntime requestValidationMode="2.0" />. After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the <pages> configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. For more information, see http://go.microsoft.com/fwlink/?LinkId=153133. Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (wresult="<t:RequestSecurityTo...").

• Simple Linux program that takes any HTTP/HTTPS request and returns a single page?

  - by ultrasawblade

  I have a Linux box operating as router. There's a NIC that's connected to the internet (WAN), a NIC connected to an 8-port GbE switch (LAN), and a NIC connected to a Linksys wireless N-router (WLAN). Routing between everything is working perfectly. I have security completely disabled on the wireless router, but the WLAN NIC is firewalled such that it will only accept DNS queries and PPTP VPN connections. Currently HTTP/HTTPS traffic and everything else is blocked. I would like to run something that listens on port 80/443 of the WLAN NIC, and, for non VPN'ed connections, given any HTTP/HTTPS request it will return a single webpage saying "Unauthenticated" and explain how to sign into the VPN. A transparent proxy seems to be what I need, but my searches all seem to direct me to Squid, which is already running on my server and seems overkill for this simple task. Is there a simpler, lightweight program out there that does just this or should I just suck it up and run two instances of Squid (or figure out how to configure it)? Or, is this entire VPN thing I'm doing complete nonsense and I should just enable encryption on the wireless router?

• F# Simple Twitter Update

  A short while ago I posted some code for a C# twitter update.  I decided to move the same functionality / logic to F#.  Here is what I came up with. 1: namespace Server.Actions 2:   3: open System 4: open System.IO 5: open System.Net 6: open System.Text 7:   8: type public TwitterUpdate() = 9: 10: //member variables 11: [<DefaultValue>] val mutable _body : string 12: [<DefaultValue>] val mutable _userName : string 13: [<DefaultValue>] val mutable _password : string 14:   15: //Properties 16: member this.Body with get() = this._body and set(value) = this._body <- value 17: member this.UserName with get() = this._userName and set(value) = this._userName <- value 18: member this.Password with get() = this._password and set(value) = this._password <- value 19:   20: //Methods 21: member this.Execute() = 22: let login = String.Format("{0}:{1}", this._userName, this._password) 23: let creds = Convert.ToBase64String(Encoding.ASCII.GetBytes(login)) 24: let tweet = Encoding.ASCII.GetBytes(String.Format("status={0}", this._body)) 25: let request = WebRequest.Create("http://twitter.com/statuses/update.xml") :?> HttpWebRequest 26: 27: request.Method <- "POST" 28: request.ServicePoint.Expect100Continue <- false 29: request.Headers.Add("Authorization", String.Format("Basic {0}", creds)) 30: request.ContentType <- "application/x-www-form-urlencoded" 31: request.ContentLength <- int64 tweet.Length 32: 33: let reqStream = request.GetRequestStream() 34: reqStream.Write(tweet, 0, tweet.Length) 35: reqStream.Close() 36:   37: let response = request.GetResponse() :?> HttpWebResponse 38:   39: match response.StatusCode with 40: | HttpStatusCode.OK -> true 41: | _ -> false   While the above seems to work, it feels to me like it is not taking advantage of some functional concepts.  Love to get some feedback as to how to make the above more “functional” in nature.  For example, I don’t like the mutable properties.

• Doing a DELETE request from <a> tag without constructing forms?

  - by Mike Trpcic

  Is there any way to force an <a href> to do a delete request when clicked instead of a regular GET? The "Rails" way is to dynamically generate a <form> tag that adds the appropriate params so that it gets routed to the right place, however I'm not too fond of that much DOM manipulation for such a simple task. I thought about going the route of something like: $("a.delete").click(function(){ var do_refresh = false; $.ajax({ type: "DELETE", url: "my/path/to/delete", success: function(){ do_refresh = true; }, failure: function(){ alert("There is an error"); } }); return do_return; //If this is false, no refresh would happen. If it //is true, it will do a page refresh. }); I'm not sure if the above AJAX stuff will work, as it's just theoretical. Is there any way to go about this? Note: Please don't recommend that I use the rails :method => :delete on link_to, as I'm trying to get away from using the rails helpers in many senses as they pollute your DOM with obtrusive javascript. I'd like this solution to be put in an external JS file and be included as needed.

• AuthnRequest Settings in OIF / SP

  - by Damien Carru

  In this article, I will list the various OIF/SP settings that affect how an AuthnRequest message is created in OIF in a Federation SSO flow. The AuthnRequest message is used by an SP to start a Federation SSO operation and to indicate to the IdP how the operation should be executed: How the user should be challenged at the IdP Whether or not the user should be challenged at the IdP, even if a session already exists at the IdP for this user Which NameID format should be requested in the SAML Assertion Which binding (Artifact or HTTP-POST) should be requested from the IdP to send the Assertion Which profile should be used by OIF/SP to send the AuthnRequest message Enjoy the reading! Protocols The SAML 2.0, SAML 1.1 and OpenID 2.0 protocols define different message elements and rules that allow an administrator to influence the Federation SSO flows in different manners, when the SP triggers an SSO operation: SAML 2.0 allows extensive customization via the AuthnRequest message SAML 1.1 does not allow any customization, since the specifications do not define an authentication request message OpenID 2.0 allows for some customization, mainly via the OpenID 2.0 extensions such as PAPE or UI SAML 2.0 OIF/SP allows the customization of the SAML 2.0 AuthnRequest message for the following elements: ForceAuthn: Boolean indicating whether or not the IdP should force the user for re-authentication, even if the user has still a valid session By default set to false IsPassive Boolean indicating whether or not the IdP is allowed to interact with the user as part of the Federation SSO operation. If false, the Federation SSO operation might result in a failure with the NoPassive error code, because the IdP will not have been able to identify the user By default set to false RequestedAuthnContext Element indicating how the user should be challenged at the IdP If the SP requests a Federation Authentication Method unknown to the IdP or for which the IdP is not configured, then the Federation SSO flow will result in a failure with the NoAuthnContext error code By default missing NameIDPolicy Element indicating which NameID format the IdP should include in the SAML Assertion If the SP requests a NameID format unknown to the IdP or for which the IdP is not configured, then the Federation SSO flow will result in a failure with the InvalidNameIDPolicy error code If missing, the IdP will generally use the default NameID format configured for this SP partner at the IdP By default missing ProtocolBinding Element indicating which SAML binding should be used by the IdP to redirect the user to the SP with the SAML Assertion Set to Artifact or HTTP-POST By default set to HTTP-POST OIF/SP also allows the administrator to configure the server to: Set which binding should be used by OIF/SP to redirect the user to the IdP with the SAML 2.0 AuthnRequest message: Redirect or HTTP-POST By default set to Redirect Set which binding should be used by OIF/SP to redirect the user to the IdP during logout with SAML 2.0 Logout messages: Redirect or HTTP-POST By default set to Redirect SAML 1.1 The SAML 1.1 specifications do not define a message for the SP to send to the IdP when a Federation SSO operation is started. As such, there is no capability to configure OIF/SP on how to affect the start of the Federation SSO flow. OpenID 2.0 OpenID 2.0 defines several extensions that can be used by the SP/RP to affect how the Federation SSO operation will take place: OpenID request: mode: String indicating if the IdP/OP can visually interact with the user checkid_immediate does not allow the IdP/OP to interact with the user checkid_setup allows user interaction By default set to checkid_setup PAPE Extension: max_auth_age : Integer indicating in seconds the maximum amount of time since when the user authenticated at the IdP. If MaxAuthnAge is bigger that the time since when the user last authenticated at the IdP, then the user must be re-challenged. OIF/SP will set this attribute to 0 if the administrator configured ForceAuthn to true, otherwise this attribute won't be set Default missing preferred_auth_policies Contains a Federation Authentication Method Element indicating how the user should be challenged at the IdP By default missing Only specified in the OpenID request if the IdP/OP supports PAPE in XRDS, if OpenID discovery is used. UI Extension Popup mode Boolean indicating the popup mode is enabled for the Federation SSO By default missing Language Preference String containing the preferred language, set based on the browser's language preferences. By default missing Icon: Boolean indicating if the icon feature is enabled. In that case, the IdP/OP would look at the SP/RP XRDS to determine how to retrieve the icon By default missing Only specified in the OpenID request if the IdP/OP supports UI Extenstion in XRDS, if OpenID discovery is used. ForceAuthn and IsPassive WLST Command OIF/SP provides the WLST configureIdPAuthnRequest() command to set: ForceAuthn as a boolean: In a SAML 2.0 AuthnRequest, the ForceAuthn field will be set to true or false In an OpenID 2.0 request, if ForceAuthn in the configuration was set to true, then the max_auth_age field of the PAPE request will be set to 0, otherwise, max_auth_age won't be set IsPassive as a boolean: In a SAML 2.0 AuthnRequest, the IsPassive field will be set to true or false In an OpenID 2.0 request, if IsPassive in the configuration was set to true, then the mode field of the OpenID request will be set to checkid_immediate, otherwise set to checkid_setup Test In this test, OIF/SP is integrated with a remote SAML 2.0 IdP Partner, with the OOTB configuration. Based on this setup, when OIF/SP starts a Federation SSO flow, the following SAML 2.0 AuthnRequest would be generated: <samlp:AuthnRequest ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" ID="id-E4BOT7lwbYK56lO57dBaqGUFq01WJSjAHiSR60Q4" Version="2.0" IssueInstant="2014-04-01T21:39:14Z" Destination="https://acme.com/saml20/sso">   <saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">https://sp.com/oam/fed</saml:Issuer>   <samlp:NameIDPolicy AllowCreate="true"/></samlp:AuthnRequest> Let's configure OIF/SP for that IdP Partner, so that the SP will require the IdP to re-challenge the user, even if the user is already authenticated: Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the configureIdPAuthnRequest() command:configureIdPAuthnRequest(partner="AcmeIdP", forceAuthn="true") Exit the WLST environment:exit() After the changes, the following SAML 2.0 AuthnRequest would be generated: <samlp:AuthnRequest ForceAuthn="true" ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" ID="id-E4BOT7lwbYK56lO57dBaqGUFq01WJSjAHiSR60Q4" Version="2.0" IssueInstant="2014-04-01T21:39:14Z" Destination="https://acme.com/saml20/sso">   <saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">https://sp.com/oam/fed</saml:Issuer>   <samlp:NameIDPolicy AllowCreate="true"/></samlp:AuthnRequest> To display or delete the ForceAuthn/IsPassive settings, perform the following operatons: Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the configureIdPAuthnRequest() command: To display the ForceAuthn/IsPassive settings on the partnerconfigureIdPAuthnRequest(partner="AcmeIdP", displayOnly="true") To delete the ForceAuthn/IsPassive settings from the partnerconfigureIdPAuthnRequest(partner="AcmeIdP", delete="true") Exit the WLST environment:exit() Requested Fed Authn Method In my earlier "Fed Authentication Method Requests in OIF / SP" article, I discussed how OIF/SP could be configured to request a specific Federation Authentication Method from the IdP when starting a Federation SSO operation, by setting elements in the SSO request message. WLST Command The OIF WLST commands that can be used are: setIdPPartnerProfileRequestAuthnMethod() which will configure the requested Federation Authentication Method in a specific IdP Partner Profile, and accepts the following parameters: partnerProfile: name of the IdP Partner Profile authnMethod: the Federation Authentication Method to request displayOnly: an optional parameter indicating if the method should display the current requested Federation Authentication Method instead of setting it delete: an optional parameter indicating if the method should delete the current requested Federation Authentication Method instead of setting it setIdPPartnerRequestAuthnMethod() which will configure the specified IdP Partner entry with the requested Federation Authentication Method, and accepts the following parameters: partner: name of the IdP Partner authnMethod: the Federation Authentication Method to request displayOnly: an optional parameter indicating if the method should display the current requested Federation Authentication Method instead of setting it delete: an optional parameter indicating if the method should delete the current requested Federation Authentication Method instead of setting it This applies to SAML 2.0 and OpenID 2.0 protocols. See the "Fed Authentication Method Requests in OIF / SP" article for more information. Test In this test, OIF/SP is integrated with a remote SAML 2.0 IdP Partner, with the OOTB configuration.

• Authenticating clients in the new WCF Http stack

  - by cibrax

  About this time last year, I wrote a couple of posts about how to use the “Interceptors” from the REST starker kit for implementing several authentication mechanisms like “SAML”, “Basic Authentication” or “OAuth” in the WCF Web programming model. The things have changed a lot since then, and Glenn finally put on our hands a new version of the Web programming model that deserves some attention and I believe will help us a lot to build more Http oriented services in the .NET stack. What you can get today from wcf.codeplex.com is a preview with some cool features like Http Processors (which I already discussed here), a new and improved version of the HttpClient library, Dependency injection and better TDD support among others. However, the framework still does not support an standard way of doing client authentication on the services (This is something planned for the upcoming releases I believe). For that reason, moving the existing authentication interceptors to this new programming model was one of the things I did in the last few days. In order to make authentication simple and easy to extend,  I first came up with a model based on what I called “Authentication Interceptors”. An authentication interceptor maps to an existing Http authentication mechanism and implements the following interface, public interface IAuthenticationInterceptor{ string Scheme { get; } bool DoAuthentication(HttpRequestMessage request, HttpResponseMessage response, out IPrincipal principal);} An authentication interceptors basically needs to returns the http authentication schema that implements in the property “Scheme”, and implements the authentication mechanism in the method “DoAuthentication”. As you can see, this last method “DoAuthentication” only relies on the HttpRequestMessage and HttpResponseMessage classes, making the testing of this interceptor very simple (There is no need to do some black magic with the WCF context or messages). After this, I implemented a couple of interceptors for supporting basic authentication and brokered authentication with SAML (using WIF) in my services. The following code illustrates how the basic authentication interceptors looks like. public class BasicAuthenticationInterceptor : IAuthenticationInterceptor{ Func<UsernameAndPassword, bool> userValidation; string realm;  public BasicAuthenticationInterceptor(Func<UsernameAndPassword, bool> userValidation, string realm) { if (userValidation == null) throw new ArgumentNullException("userValidation");  if (string.IsNullOrEmpty(realm)) throw new ArgumentNullException("realm");  this.userValidation = userValidation; this.realm = realm; }  public string Scheme { get { return "Basic"; } }  public bool DoAuthentication(HttpRequestMessage request, HttpResponseMessage response, out IPrincipal principal) { string[] credentials = ExtractCredentials(request); if (credentials.Length == 0 || !AuthenticateUser(credentials[0], credentials[1])) { response.StatusCode = HttpStatusCode.Unauthorized; response.Content = new StringContent("Access denied"); response.Headers.WwwAuthenticate.Add(new AuthenticationHeaderValue("Basic", "realm=" + this.realm));  principal = null;  return false; } else { principal = new GenericPrincipal(new GenericIdentity(credentials[0]), new string[] {});  return true; } }  private string[] ExtractCredentials(HttpRequestMessage request) { if (request.Headers.Authorization != null && request.Headers.Authorization.Scheme.StartsWith("Basic")) { string encodedUserPass = request.Headers.Authorization.Parameter.Trim();  Encoding encoding = Encoding.GetEncoding("iso-8859-1"); string userPass = encoding.GetString(Convert.FromBase64String(encodedUserPass)); int separator = userPass.IndexOf(':');  string[] credentials = new string[2]; credentials[0] = userPass.Substring(0, separator); credentials[1] = userPass.Substring(separator + 1);  return credentials; }  return new string[] { }; }  private bool AuthenticateUser(string username, string password) { var usernameAndPassword = new UsernameAndPassword { Username = username, Password = password };  if (this.userValidation(usernameAndPassword)) { return true; }  return false; }} This interceptor receives in the constructor a callback in the form of a Func delegate for authenticating the user and the “realm”, which is required as part of the implementation. The rest is a general implementation of the basic authentication mechanism using standard http request and response messages. I also implemented another interceptor for authenticating a SAML token with WIF. public class SamlAuthenticationInterceptor : IAuthenticationInterceptor{ SecurityTokenHandlerCollection handlers = null;  public SamlAuthenticationInterceptor(SecurityTokenHandlerCollection handlers) { if (handlers == null) throw new ArgumentNullException("handlers");  this.handlers = handlers; }  public string Scheme { get { return "saml"; } }  public bool DoAuthentication(HttpRequestMessage request, HttpResponseMessage response, out IPrincipal principal) { SecurityToken token = ExtractCredentials(request);  if (token != null) { ClaimsIdentityCollection claims = handlers.ValidateToken(token);  principal = new ClaimsPrincipal(claims);  return true; } else { response.StatusCode = HttpStatusCode.Unauthorized; response.Content = new StringContent("Access denied");  principal = null;  return false; } }  private SecurityToken ExtractCredentials(HttpRequestMessage request) { if (request.Headers.Authorization != null && request.Headers.Authorization.Scheme == "saml") { XmlTextReader xmlReader = new XmlTextReader(new StringReader(request.Headers.Authorization.Parameter));  var col = SecurityTokenHandlerCollection.CreateDefaultSecurityTokenHandlerCollection(); SecurityToken token = col.ReadToken(xmlReader);  return token; }  return null; }}This implementation receives a “SecurityTokenHandlerCollection” instance as part of the constructor. This class is part of WIF, and basically represents a collection of token managers to know how to handle specific xml authentication tokens (SAML is one of them). I also created a set of extension methods for injecting these interceptors as part of a service route when the service is initialized. var basicAuthentication = new BasicAuthenticationInterceptor((u) => true, "ContactManager");var samlAuthentication = new SamlAuthenticationInterceptor(serviceConfiguration.SecurityTokenHandlers); // use MEF for providing instancesvar catalog = new AssemblyCatalog(typeof(Global).Assembly);var container = new CompositionContainer(catalog);var configuration = new ContactManagerConfiguration(container); RouteTable.Routes.AddServiceRoute<ContactResource>("contact", configuration, basicAuthentication, samlAuthentication);RouteTable.Routes.AddServiceRoute<ContactsResource>("contacts", configuration, basicAuthentication, samlAuthentication); In the code above, I am injecting the basic authentication and saml authentication interceptors in the “contact” and “contacts” resource implementations that come as samples in the code preview. I will use another post to discuss more in detail how the brokered authentication with SAML model works with this new WCF Http bits. The code is available to download in this location.

• I am getting a 400 Bad Request error when using Nginx and PHP-FPM, why?

  - by Bob

  I am trying to run a website (that requires PHP - it technically doesn't require MySQL at this time, but it may sometime in the near future as I continue developing it, so I went ahead and installed that as well) using nginx 1.2.4 and PHP-FPM 5.3.3 on Ubuntu 12.04.1 LTS. As far as I know, I haven't done anything wrong, but clearly something is not quite right - I seem to be getting a 400 Bad Request error whenever I try to browse to my website. I've been mostly following one guide, and I've done more or less everything it recommends, except for not setting up PHP-FPM to use a Unix Socket and I used service as opposed to /etc/init.d/ when starting/stopping nginx, PHP, and MySQL. Anyways, here are my relevant configuration files (I have only censored personal/sensitive details, like my domain name - which contains my real name): /etc/nginx/nginx.conf user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 15; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; ## # nginx-naxsi config ## # Uncomment it if you installed nginx-naxsi ## #include /etc/nginx/naxsi_core.rules; ## # nginx-passenger config ## # Uncomment it if you installed nginx-passenger ## #passenger_root /usr; #passenger_ruby /usr/bin/ruby; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } /etc/nginx/sites-enabled/subdomain.mydomain.net server { listen 80; # listen for IPv4 listen [::]:80; # listen for IPv6 server_name www.subdomain.mydomain.net subdomain.mydomain.net; access_log /srv/www/subdomain.mydomain.net/logs/access.log; error_log /srv/www/subdomain.mydomain.net/logs/error.log; location / { root /srv/www/subdomain.mydomain.net/public; index index.php; } location ~ \.php$ { try_files $uri =400; include fastcgi_params; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/subdomain.mydomain.net/public$fastcgi_script_name; } } All the directories listed in the configuration files above are correct on my server (to the extent of my knowledge). I have not included /etc/php5/fpm/pool.d/www.conf or /etc/php5/fpm/php.ini in this post as they're rather long, but I have posted them on Pastebin: http://pastebin.com/ensErJD8 and http://pastebin.com/T23dt7vM, respectively. Although, the only thing I've changed in either of the two files was in php.ini, where I set expose_php to off so as to hide the .php file extension from users. What can I do to resolve my issue? Please let me know if I need to supply any additional details.

• Preserving case in HTTP headers with Ruby's Net:HTTP

  - by emh

  Although the HTTP spec says that headers are case insensitive; Paypal, with their new adaptive payments API require their headers to be case-sensitive. Using the paypal adaptive payments extension for ActiveMerchant (http://github.com/lamp/paypal_adaptive_gateway) it seems that although the headers are set in all caps, they are sent in mixed case. Here is the code that sends the HTTP request: headers = { "X-PAYPAL-REQUEST-DATA-FORMAT" => "XML", "X-PAYPAL-RESPONSE-DATA-FORMAT" => "JSON", "X-PAYPAL-SECURITY-USERID" => @config[:login], "X-PAYPAL-SECURITY-PASSWORD" => @config[:password], "X-PAYPAL-SECURITY-SIGNATURE" => @config[:signature], "X-PAYPAL-APPLICATION-ID" => @config[:appid] } build_url action request = Net::HTTP::Post.new(@url.path) request.body = @xml headers.each_pair { |k,v| request[k] = v } request.content_type = 'text/xml' proxy = Net::HTTP::Proxy("127.0.0.1", "60723") server = proxy.new(@url.host, 443) server.use_ssl = true server.start { |http| http.request(request) }.body (i added the proxy line so i could see what was going on with Charles - http://www.charlesproxy.com/) When I look at the request headers in charles, this is what i see: X-Paypal-Application-Id ... X-Paypal-Security-Password... X-Paypal-Security-Signature ... X-Paypal-Security-Userid ... X-Paypal-Request-Data-Format XML X-Paypal-Response-Data-Format JSON Accept */* Content-Type text/xml Content-Length 522 Host svcs.sandbox.paypal.com I verified that it is not Charles doing the case conversion by running a similar request using curl. In that test the case was preserved.

• How to get correct Set-Cookie headers for NSHTTPURLResponse?

  - by overboming

  I want to use the following code to login to a website which returns its cookie information in the following manner: Set-Cookie: 19231234 Set-Cookie: u2am1342340 Set-Cookie: owwjera I'm using the following code to log in to the site, but the print statement at the end doesn't output anything about "set-cookie". On Snow leopard, the library seems to automatically pick up the cookie for this site and later connections sent out is set with correct "cookie" headers. But on leopard, it doesn't work that way, so is that a trigger for this "remember the cookie for certain root url" behavior? NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:uurl]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setValue:@"keep-live" forHTTPHeaderField:@"Connection"]; [request setValue:@"300" forHTTPHeaderField:@"Keep-Alive"]; [request setHTTPShouldHandleCookies:YES]; [request setHTTPBody:postData]; [request setTimeoutInterval:10.0]; NSData *urlData; NSHTTPURLResponse *response; NSError *error; urlData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSLog(@"response dictionary %@",[response allHeaderFields]);

I set up the request to go to a mock server which sleeps for 30 seconds. When I call BeginGetResponse, the application just waits at that line of code for the response. I want it to carry on with the app, and then just run the callback whenever it finishes. This code is run from a web page, and my callback just logs the response and sends an email. I don't want to use to have to wait for the response.

• FancyURLOpener failing since moving to python 3.1.2

  - by Andrew Shepherd

  I had an application that was downloading a .CSV file from a password-protected website then processing it futher. I was using FancyURLOpener, and simply hardcoding the username and password. (Obviously, security is not a high priority in this particular instance). Since downloading Python 3.1.2, this code has stopped working. Does anyone know of the changes that have happened to the implementation? Here is a cut down version of the code: import urllib.request; class TracOpener (urllib.request.FancyURLopener) : def prompt_user_passwd(self, host, realm) : return ('andrew_ee', '_my_unenctryped_password') csvUrl='http://mysite/report/19?format=csv@USER=fred_nukre' opener = TracOpener(); f = opener.open(csvUrl); s = f.read(); f.close(); s; For the sake of completeness, here's the entire call stack: Traceback (most recent call last): File "C:\reporting\download_csv_file.py", line 12, in <module> f = opener.open(csvUrl); File "C:\Program Files\Python31\lib\urllib\request.py", line 1454, in open return getattr(self, name)(url) File "C:\Program Files\Python31\lib\urllib\request.py", line 1628, in open_http return self._open_generic_http(http.client.HTTPConnection, url, data) File "C:\Program Files\Python31\lib\urllib\request.py", line 1624, in _open_generic_http response.status, response.reason, response.msg, data) File "C:\Program Files\Python31\lib\urllib\request.py", line 1640, in http_error result = method(url, fp, errcode, errmsg, headers) File "C:\Program Files\Python31\lib\urllib\request.py", line 1878, in http_error_401 return getattr(self,name)(url, realm) File "C:\Program Files\Python31\lib\urllib\request.py", line 1950, in retry_http_basic_auth return self.open(newurl) File "C:\Program Files\Python31\lib\urllib\request.py", line 1454, in open return getattr(self, name)(url) File "C:\Program Files\Python31\lib\urllib\request.py", line 1628, in open_http return self._open_generic_http(http.client.HTTPConnection, url, data) File "C:\Program Files\Python31\lib\urllib\request.py", line 1590, in _open_generic_http auth = base64.b64encode(user_passwd).strip() File "C:\Program Files\Python31\lib\base64.py", line 56, in b64encode raise TypeError("expected bytes, not %s" % s.__class__.__name__) TypeError: expected bytes, not str
